Starcraft – How to land a building precisely to connect to a techlab/reactor in Starcraft 2

starcraft-2starcraft-terran

When I am doing the swap-around, how can I be sure to land the building at the precise location to connect to the reactor or the tech-lab?

I see pros do it seamlessly, but when I do it, I have to lift-off and re-land multiple times till I make it connect successfully, and that by luck.

Is there an indicator that shows me the spot to land to connect to a building extension before I land?

The UI of Starcraft 2 should show you an outline of the building after you have hit the land command. This outline will allow you to place the building correctly.

When you invoke the land option, you will see two outlines: one where your mouse is and one beside the tech tab/reactor:

Simply move your mouse so that the outlines overlap:

Lining up the mouse outline with the outline next to the add-on.

Then, click the left mouse button. Your building will start flying toward the target location:

If you lined everything up correctly, it will land right beside the add-on:
